Reply To: OTG cable with charge

[CH]

I have one like in your link and another that looks like the one Chris (I think) recommended.

The first one has some kind of mechanical relay inside which seems wierd.

The latter is better in terms of simultaneous charging and hub but neither allow full charge speed which means the tablet can’t charge fast enough when the screen is on. So eventually the battery discharges. Both also have issues

I can only charge at about 0.5A whereas with a straight cable I get about 1.1-1.2A. The first one I bought claims high charge rates and lower gauge cables, but it doesn’t seem to work for me. The other larger problem for me is that if unplugged (or power is removed from the hub in charging + hub mode), the tablet often needs to be rebooted. Also if power is removed, the whole hub unplugs so devices plugged into the hub now longer work. I want to leave the hub plugged in and turn power on and off externally.
